Why this quadrant

UST held its peg only while people wanted LUNA, and LUNA had value only while people held UST. Each was the other's collateral. That works until it does not, and when it stopped it took six days to go from a year of calm to nothing. The reclassification came later, when a 2021 bailout by Jump Trading turned out to have been kept from investors.
